COCK.

SPECIFICATION forming part of Letters Patent No. 269,886, dated January 2, 1853.

' Application inea nimh se, rss2. (No mont-i.)

To all whom it Imay concern: V

Be it known that I, JAMES SEMPLE, ot' Uineinnati, Hamilton county, Ohio, have invented a new and useful Improvement 'rn Cocks, of which the following is a specification.

My invention is an improvement in those cocks or faucets in which a small ventage with easily-operated valve, that closes against the pressure of the conlned liquid, controls the action of a much larger valve and corresponding opening capable of any desired copiousness of delivery.

In the accompanying drawings, Figures I, 3, 5, and 7 are axial sections, which respectively show in the closed or inactive condition foin s lightly diverse forms oradaptations of my invention, and Figs. 2, 4, G, and S are respect- Aively similar sectionsof the same forms in the open condition.

I will rst describe the essential parts common to everyform ot' my improvementto wit, a service-pipe, A, a discharge-pipe, B, a large port, C, from service-pipe into discharge-pipe, controlled by a valve, D, preferablyT of rubber, whose outer area is considerablyvgreater than thaton the service side or toward the pipe A, a minute duct, E,t'roxn service-pipe through valve D-into a chamber, F-which has a ventage, G, which may either empty into the general discharge-pipe, as in Figs. 1,2, 3,4, 5, and 6, or independently thereof', asin Figs. 7 and 8. rlhe area ot' effective delivery ot' ventage G, while slightly greater than that ot' duct E, is very much less than that of the main port C. Controlling the ventage G is a small valve, H, which is caused to shut against the Dressur-e ofthe confined liquid by any suitable meanssuoh as by spring I, as in Figs. l and 2, or by a hand-operated lever-screw, J, as in Figs. J5, 4, 5, and 6, or by the buoyant action of a float, K, as in Figs. 7 and S-and may be capable ot' being opened by hand, as in Figs. 1, 2, 3, 4, 5, and 6, or by the weight of a float, as in Figs. 7 and S.

Having described the features com mon to the several forms of my improvement, I now proceed to explain adaptation of the improvelnent to several kinds of faucets.

Figs. 1 and 2 are axial sections (Fig. 1 in the closed and Fig. 2 in the open condition) ot' a discharge-cock applicable to water-closets, 5to.

The main port or valve-seat C is somewhat elevated for the dat sole ot'a rubber valve, D. Said valve is pierced by a duct that consists ot' a small tube, E, withone or more minute outlets, e, capable of being partially closed by means of a screw-plug, Il. A metallic. collar, M, secured to the tube E, discharges theJ functions of a backing or follower to the rubber valve D.

The small controlling-valve H is secured by stern N to a water-tight plunger, O, within a cylindrical neck, P, and is provided with a handle, Q, part-ly outside of said neck. The said valve H has a rubber sole, h, which in the closed condition of the cock rests upon and closes the elevated neck.

The port or ventage G, when open, communicates with the discharge B, through a passage, It, in the wall ot' chamber F.

The main valve D consists of a disk of sufficient diameter to serve as a gasket, d, between the marginal tlangef of chamberF and the flange a of the casting'A B, to which it is secured by bolts S. The portion ofthevalve D which rests upon the port C when closed is thickened by a boss, d. The valve-gasket d, being perforated (cl) where it registers with the passage It, ott'ers no obstruction to said passage, and yet prevents any leakage therefrom.

A description ot' the opera-tion of this form of'lny device is in the main explanatory of all, and is as follows: In the normal or closed condition ofthe cock (see Fig. l) the pressures in pipe A and chamber F are manifestly equal,

and the side ot' the valve which is directed toward the chamber F being greater than that presented to the interior of the pipe A, it follows that the valve closely presses the edges ot' the port C, and by so doing closes the pipe A. Now, let the valve H be raised. This action, opening the ventage G, offers an exitt'or the contents ol' the chamber F, which taking place permits a flow of the contents of pipe A through duct E. The upward current thus initiated reverses the relative pressure against the respective under and upper sides of the valve D, and, lifting the latter, opens the large port C, which then discharges direct into the discharge-pipe I3, as indicated by arrows in Fig. 2. This continues as long as the valve H is held open,the comparatively large passage C being maintained in a fully or IOO slightly open condition, at discretion of theuser, by the slight effort required for maintaining at a more or less elevated position the valve H. Upon depression of valve H to a point at which the velocity of the current is insutiicient to overcome the inequality of areas ot' the top and bottom of 'the valve D, the valve D will slowly sink, and thus gradually close the main issue, and such sinking will be accelerated by complete closure of valve H until, the chamber F becoming full ot' water, received through smalldnct E, the main valve Vl) resumes its closed condition and the fiow ceases. vrlhe closure ot' main valve l) after that of the valve II may be expedited or retarded by turning oi'` the screw L to the left or to the right. By this means the vflow may be regulated, and concussion and 1ater-ram prevented. In addition to this automatic regulation, the person controlling the handle Q is able at will to adjust the llow atany instant as above initiated.

I do not restrict myscli to the above-dcscribed mode of automatic closure ot' the valve H, and consequently of" the cock, but, 011 the contrary, may make the closure at the cock positive by means oll a cam-lever or other customary mechanical expedient.

Figs. 3 and 4 are axial sections-Fig. in the closed and Fig. 4 in the open conditionofan embodiment of my invention ola slightlydi'erenttorm to that last described. In this arrangement the boss d. oi" the valve D is of the conical shape represented, to fit a correspondingly conical seat, (l. 'lhe valve Il is also conical to tit a seat, G, ot' corresponding` form. Both depression and elevation ot' said valve is etl'ected by a lever-screw, J, thus securing a positive action in both directions.

The arrangement shown in Figs. 5 and (i dif'- fer from that last described only in that, in stead ot' the single conical valve IiI, there is united by stem II with such valve an inverted cone, H, which, in the open condition ot' valve Il, as shown in Fig. b, closes down upon a corresponding seat, G', and in so doing shuts a wasteway, T, which is opened by reversal of the valve, as in Fig. 5, so as then to permit the escape of whatever water may be lett above the valve after closure, and thus avoid danger of freezing, tvc.

Fig. 7-shows in the closed and Fig. 8 'in the open condition such modification of the form shown in Figs. l and 2 as to adapt my improvement to perform the duties of a self-acting tank-cock. In this form the ventageGand thedischarge-pipeB both deliver intothe same tank, U, the valve H heilig opened and closed automatically7 by the sinking and rising of aball-tloat, K.

I am aware that it is not new to construct the main valve of a cock or faucet of a flexible diaphragm traversed by a duct whose delivery, being controlled by another valve, serves to open or close said main valve, and I therefore malte no claim to such a device, broadly or separately considered; nor do I claim the use ot' regulating` adjustable plugs, nor of douhle conical valves, nor ot' wasteways, such devices being` old and well known.

I claim herein as new and lny inventionl. In combination with the main valve I) and a controlling-valve, the regulating-duct E, adjustable in its delivery7 by means ot' plugr L, substantially ts and for the purpose designated.

2. In the described combination with main opening C and its valve D, and with the duct E in said valve, adjustable in its delivery by means of plug L, the double conical controlling-valve II H II in the corresponding donble-seated chamber l), with wastevay T, substantially as set forth.

In testimony ot' which invention I hereunto set my hand.

, JAMES SEMPLII.
